Week 3 Initial Post Pain is an unpleasant sensory and emotional experience arising from actual or potential tissue damage or described in terms of such damage (Huether & McCance, 2017). Pain encompassed dynamic interactions between physical, cognitive, spiritual, emotional, and environmental factors and cannot be categorized as only response to injury. Pain is whatever the person is experiencing that moment and wherever it exists as explained by that individual. Patients are often asked to rate their pain on a scale from 1- 10: mild (1-4), moderate (5-6), and severe (7-10). Sometimes smiling and frowning faces are used as visual aids to help both doctor and patient convey what the numbers signify (Carteret, 2010). Pain is one of the most common symptom for which a person seeks medical attention. It causes physical, psychosocial & psychological distress to a person, considerably interfering on their personal and social lives. Pathophysiology of Pain The processing of harmful stimuli through a normally functioning nervous system is called nociception. Nociceptors or pain receptors, are free nerve endings in the afferent peripheral nervous system ( Huether & McCance, 2017). Nociceptors have a peripheral and central axonal branch that innervates their target organ and the spinal cord. Nociceptors are spread throughout the body so the sensitivity to pain differs based on their location.
